Abstract

The invention discloses a medium-high voltage rotary transmission conductive gas insulation device which comprises a shell provided with a sealing cavity; a conductive circular ring assembly which is arranged in the sealing cavity; and an inflation valve which is arranged on the shell, and is communicated with the sealing cavity. The shell is provided with the sealing cavity for containing the conductive circular ring assembly, and meanwhile the shell is provided with the inflation valve communicated with the sealing cavity, so that gas can be inflated into the sealing cavity through the inflation valve, and then the air pressure in the sealing cavity is increased. According to the Pahen's law, the gas pressure and the breakdown voltage are positively correlated within a certain range, namely the threshold value of the breakdown voltage can be increased by the high gas pressure, the occurrence of electric breakdown conditions is reduced, short circuit between transmission channels in the conductive ring assembly or short circuit of the transmission channels to the ground is prevented, and the safety and the reliability are improved.

Description

technical field [0001] The invention relates to the field of power transmission, in particular to conductive gas-insulated equipment for medium and high voltage rotary transmission. Background technique [0002] With the rapid development of the new energy field, wind power, as a clean energy, has important development significance. As an essential core component in wind power generation equipment, the conductive ring has a great influence on the reliability and safety of its work. [0003] The existing conductive ring, under the working environment of high voltage, such as 40.5kV voltage level, may cause electrical breakdown due to excessive voltage, resulting in safety problems such as short circuit of adjacent transmission channels, short circuit of transmission channels to ground, etc. . Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention propo...
